Description

The invention relates to an inclined elevator, in particular personal nominal and / or furniture elevator with several of two Rope-like guide rails formed telescope shots for a load handler attached to it, under Ver use of a motorized extension device between the bottom guide rail and the next following guide rail and using trained as pin chains so-called finite traction means for the forced extension of the the second lowest guide rail following guide rails, the bolt chains from a fixed point at the top of one Guide rail over a pulley at the top of each following guide rail to a fixed point at the lower end of the next following guide rail.

The invention is based on an older proposal by the applicant (second-order hour in part according to file number P 36 28 447.5), for that for the forced extension of the second lowest telescope shot following telescopic shots in the manner described guided pin chains serve. The pin chains occur at the  older application according to P 36 28 447 in place of the from the Hrs d. T. (DE-PS 31 37 845) known, designed as ropes so-called "endless traction means", whereby by the proposed Bolt chains have the advantage of reduced rope elasticity and so that the advantage of more precise driving is achieved.

In the older application according to P 36 28 447, however, Teles Cop shot use, which consists of parallel to each other Guide rails are formed, which are like a ladder are connected by several cross bars. The guide rails are approximately U-shaped profiles of a Ausgestal in cross section tion form, as known from DE-OS 35 41 836 became. Such guide rails are advantageous for the transport of material, for example from ground level Area to the roof of a house; between these guide rails however, the motorized extensions are unprotected directions (multiple sheared winch rope) between the lowest and the next telescopic shot as well as the flyer chains designed so-called "finite traction means" for the forced extension of the next telescopic shots.

The subject of registration after the second-hour hour d. T. belonging application P 36 28 447 is thus advantageous for furniture suitable for lifts; not however for passenger lifts; to that extent the claimed genus goes over the second tier Std. according to P 36 28 447.

The object of the invention is to provide an inclined elevator to improve the above-mentioned genus so that it especially especially as a passenger elevator or combined passenger and / or Furniture elevator can be used, i.e. the bending stiffness and torsion resistance of the rails thanks to an improved profile form increase while minimizing the game an exact guidance of the guide rails to each other is guaranteed should be. Next should refer to the so-called "finite Traction means "find a traction means used for educating  the elasticity of the traction means minimized to a negligible level, being beyond in connection with the profiling one against weather Rivers largely protected arrangement of the traction means should be.

The invention solves the problem with the teaching according to saying 1.

In the case of the d. T. (DE-OS 35 41 836) known telescope shots are those with their thighs facing each other U-profiles of the guide rails are ver verified like a ladder bound so that only in the area of the upper about horizontal legs of these profiles the top and Under rolls of the load handler can be performed. This results in a very small difference when driving over from one rail joint to another, so that the formation of the Storage of the guide rollers of the load handler is not very difficult prepare.

For this reason there is a prejudice against a closed one Training the guide rails because they do not have their ge entire length can be connected to each other by cross bars can, and the training of the storage of the guide rollers due to the large difference when driving over the rail joints is difficult.

The invention frees itself from this prejudice, so that in Result telescopic shots are formed which are only in the area the upper ends of the guide rail under a cross belt are connected.

By training as a closed hollow profile, maximum Guiding and sliding properties of the individual Pro file reached each other, being defined by creating Channels between the individual telescopic shots a protected  Arrangement for the forced extension of each telescope shots required traction is given.

Further features of the invention are defined by the subclaims indicates.

According to claim 2 takes place as a motor-driven extension device a double between the bottom and the following telescopic shot Acting hydraulic thrust piston gear use what the The advantage is that by means of the hydraulic thrust piston gear both an exact extension and an exact (force driven) retraction of the Te following the lowest telescopic shot Lescope shot is possible. However, the invention is not ver leave if in instead of the hydraulic thrust piston gear in a known manner use a winch-driven rope finds.

Since - with the exception of the guide rails of the lowest telescopic section - all guide rails of the following telescopic sections are connected only in the area of their upper end by a cross belt, the cross belt serves to displace the deflection rollers for the pin chains and preferably the deflection roller for a return cable (claims 3- 5). The use of a return rope has the advantage that when the second lowest telescopic section is actively retracted compared to the lowest telescopic section, all other telescopic sections in the sense of "driving in" are taken along. This is particularly important if one starts from the consideration that the top telescope shot is anchored, for example, to a building, whereby it was accidentally forgotten to loosen the anchor before retracting the hydraulic thrust piston gear. The uppermost telescopic section could pull out of the second uppermost if no suitable means are provided to prevent the uppermost telescopic section from being pushed out completely from the second uppermost. Since the guide rails are inserted into one another as closed profiles and are guided against one another with as little play as possible, the assignment of limit stops is difficult, so that in this case a return cable that limits the extension path and at the same time causes the forced insertion is a technically advantageous solution, especially as claimed in claim 6 the pin chains and the return cables are protected in a side-by-side arrangement in defined channels.

When applying the invention to a Trans port of furniture serving elevator is proposed every Füh to assign two pin chains, both of which as the Serve load-bearing work chains, i.e. together the burden Serve when extending the telescopic shots while is proposed in a passenger elevator according to the invention, that only one of the two pin chains is used for forced extension, while the second pin chain to a certain extent unloaded or only slightly charged and in the event of breakage the so-called work chain serves as a safety chain (claim 7).

Claims 9-12 relate to the design of the invention according to the profile. After that, the innermost (top) profile is as closed rectangular profile formed, which - in the count from the inside to the outside - is enclosed by a following profile, which is directed outwards on a longer side of the rectangle Has offset so that between the inner and the next following profile a defined guide channel for the pin chain and possibly a return rope is formed. The latter Profile is in turn a profile with a rectangular cross section enclosed; the bend of what follows the innermost profile Profile is made so that the outside of the bend in turn two guide channels are formed in mirror image to each other, which can accommodate the following pin chains. Defined by means arranged wear inserts, which are preferably only in the lower and the upper area of the respective profiles are provided almost play-free routing of the profiles to each other is possible.

As a result, an inclined elevator is achieved, which in contrast to the well-known inclined lifts the high security requirements for passenger transportation.  

The invention is described below using an exemplary embodiment an inclined elevator with, for example, six telescopic sections explained in more detail.

Show it:

Fig. 1 is a perspective view of the overall view of a sloping elevator,

Fig. 2 shows the lowest and second lowest telescopic section according to FIG. 1 in an exploded view,

Fig. 3 shows a section III-III according to Fig. 2,

Fig. 4 is a completed view of FIG. 3,

Fig. 5 shows the chain and wire rope guide Schedule

Fig. 6 shows a cross section through a telescopic sections formed from six inclined lift, with a seventh Teles kopschuß is indicated by dash-dotted lines and the profile of the pin chains has been drawn in,

FIG. 7 shows a representation according to FIG. 6, the course of the return cable being drawn in.

The inclined elevator 8 shown in FIG. 1 has a lower telescopic section 9 'and five further telescopic sections 9 extendable relative to this. The telescopic section 9 'is supported on a chassis 10 designed as a single-axle trailer, which can be supported over a large area in the use position via support spindles 12 . During driving, the lower telescopic section 9 'is supported on a support 15 ; in the position of use, the support is provided in the desired inclined position via a telescopic support 16 . With 14 a turntable is designated, which enables pivoting in the lateral direction.

The designated load carrying means 11 (for example, a furniture platform or a passenger cabin) is operated via a not shown Darge via a pulley 26 load rope by means of winches 13 .

The individual guide rails were designated 1-6 (or 7 , Fig. 6 and 7).

In Fig. 2 it is clear that the guide rails belonging to a telescopic section 9 (for example 5 ) can only be connected to one another in the region of their upper end 19 by a cross belt 20 provided with stiffeners 25 and inserted in the direction of arrow 31 into the underlying telescopic section. Only the guide rails 6 of the lower telescopic section 9 'are connected by another cross belt 29 for the purpose of displacement on the chassis 10 in the region of its lower end 21 .

From Fig. 1 and 5 it can also be seen that a doppelwir kendes hydraulic thrust piston transmission 17 is fixed with its cylinder 28 in the region of the cross belt 29 , with its associated piston rod 27 an opening 22 in the cross belt 20 of the telescope shot 9 'passes through and with the free end of the piston rod 27 (see FIG. 5) on the cross belt 20 of the guide rail 5 is closed.

. In the representation of the chain or rope guide plan of Figure 5 in conjunction with Figures 6 and 7, it was assumed that, when using one as a passenger lift -. Preferably as a leaf chain trained - pin chain as work string A and a second pin chain as a safety chain S is used. Two pin chains are thus assigned to each guide rail. Starting from the lowest guide rail 6 , the work chain A and the safety chain S run from an upper fixed point P at the upper end 19 of the guide rail 6 via a deflection roller U on the cross belt 20 in the region of the guide rails 5 to a lower fixed point P 'of the guide rail 4 . Correspondingly, the next following pin chains run from the upper end of the guide rail 5 via the deflection roller U at the upper end of the guide rail 4 to a fixed point at the lower end of the guide rail 3 and so on.

The return cable R (see. Fig. 5) is each guided from an upper fixed point P '' of the guide rail 6 via a guide roller U 'at the lower end of the guide rail 5 to a fixed point P ''' at the upper end of the guide rail 4 , that is following return rope is guided from an upper fixed point on the guide rail 5 via a deflection roller at the lower end of the guide rail 4 to an upper fixed point of the guide rail 3 and so on.

As shown in FIGS. 4, 6 and 7 designate are, by another court ended offsets of each to a telescope runner 9 and 9 'associated with the guide rails 2, 4 and 6 in conjunction with the straight sides of the rectangle of the guide rails 1, 3 and 5 (as well as if necessary 7 ) defined guide channels K 1 - K 5 are created, in which both the pulleys U (see FIG. 6) for the deflection of the pin chains and the pulleys U '(see FIG. 7) for the deflection of the return rope R are arranged. As can be seen from FIG. 6, the deflection rollers U for the bolt chains (work chain A or safety chain S ) are mounted on bearings 23 of the associated telescopic sections.

From Fig. 6 it can also be seen that wear inserts 24 are arranged on the mutually facing surfaces of the individual profiles, which define the predetermined play between the individual guide rails 1-6 or 7 .

With reference to the guide rail 7 it can be seen that when additional guide rails ( 7 and following) are assigned, the profile can be changed by increasing the profile corner 30 to increase the stiffness; however, it is crucial to ensure an adequately large additional channel, designated K 6 , for the pin chain and the return cable.
